Why do people lie to impress people?

I have observed in my life that many of my own friends tell lies so frequently to impress their loved ones. why don't people understand that "IF WINTER COMES SPRING CANNOT BE FAR BEHIND". the lies that they tell will not last longer. the moment people realize that they were being misguided by the disguised cobwebs the whole respect, affection, turns into anger, remorse, hatred. All i wanted to stress is that there are other ways that people impress others, like with their good character.
Friends suggest some methods for impressing your loved ones.. let this discussion be a guide to those people who intend to impress.
